Let dimes = d and quarters =q

D + q = 50

D= 50-q

0.10d + 0.25Q = 7.70

Replace d with 50-q:

0.10(50-q) + 0.25q = 7.70

Simplify:

5 -0.10q + 0.25q = 7.70

5 + 0.15q = 7.70

Subtract 5 from both sides:

0.15q = 2.70

Divide both sides by 0.15:

Q = 2.70 / 0.15

Q = 18

D = 50-18 = 32

There are 32 dimes and 18 quarters

Compare and Contrast: Below are two equations. Solve each equation and compare the two solutions. Choose the statement that is t
grin007 [14]
Equation #1:
|2x - 3| = 17
The first solution is
2x - 3 = 17
2x = 17 + 3 = 20
x = 10
The second solution is
3 - 2x = 17
-2x = 17 - 3 = 14
x = -7
The solutions are x = 10 or x = -7.

Equation #2:
|5x + 3| = 12
The only solution is
5x + 3 = 12
5x = 12 - 3 = 9
x = 9/5

Let us examine the given answers.
a. Equation #1 and #2 have the same number of solutions.
    FALSE
b. Equation @1 has more solutions than Equation #2.
    TRUE
c. Equation #1 has fewer solutions than equation #2.
    FALSE
d. None of the statements a,b, or c apply.

Ray is buying some ginger roots to brew some fresh ginger ale. The price of the ginger root is g, and Ray has a coupon for 10% o
kondaur [170]

Step-by-step explanation:

Comparision: Let say you buy chocolate that cost $1. And there was luckily a coupon, for 10% off.

That means after applying the coupon, you will only pay 90% of the original price. Which is

0.9(1) = 0.9

which equals 90 cents.

So let go back to this problem and apply similar thinking.

The price of the original root is g, so for the original price column, check the 3rd cell, g.

Use our comparision problem, by applying the coupon to the chocolate, you will save

1 - 0.9 = 0.1

which is 1/10 of the original price.

In this equation, we can represent this as 0.1g.

So for the second column, shade in 5th cell, 0.1g.

The price would be

(0.9)1 = 0.9

So our equation for this equation will be

0.9g.

So for third column, shade in 1st cell, 0.9g.

What is the common difference of the following sequence? 4.3,5,7,9,11___<br>5.16,19,22,25__​
myrzilka [38]

Answer:

Step-by-step explanation:

4). Given sequence → 3, 5, 7, 9, 11........

    Common difference of an arithmetic sequence is defined by,

    Common difference = Successive term - previous term

                                       = 2nd term - 1st term

                                       = 5 - 3

                                       = 2

5). Given sequence → 16, 19, 22, 25........

    Common difference of an arithmetic sequence = Second term - first term

                                                                                    = 19 - 16

                                                                                     = 3
